Application led october 22, 1914. Serial No. 867,989.

To all whom it may concern:

Be it known that I, WILLIAM A. GEIGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Railway-Car Side Bearings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a para of this specification.

This invention relates to improvements in railway Icar side bearing.

The object of the invention is to provide a side bearing for railway cars which consists of few parts that may be cheaply and easily manufactured and assembled and which will provide a bearing efficient in operation.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices as ,herein shown, described or claimed. And although I herein show and describe in detail one form of my improve-- ments, yet I do not wish to be confined to the details shownand described, inasmuch as I am aware that various changes and modifications may be made in the arran ement and details of the parts without eparting from the spirit of the invention, and I contemplate all such changes and moditications as fall within the scope of the claims forming a part hereof.

In the drawing, Figure 1 is an elevational view of a bodyv and truck bolster of a railway car, showing my improvements in connection therewith. Fig. 2 is an enlarged vertical sectional vie@ taken substantially on the line 2-2 of Fig. 1 and showing more particularly the improved side bearing, the roller being shown in side elevation and Fig. 3 is a similar sectional view taken substantially on the line 3 3 of Fig. 2.

In said drawing 10 denotes the truck bolster which is swiveled in the usual manner to the body bolster l11a-nd, as shown, the body bolster is provided with an integral bearing plate 12 on each side of the king pin.- Coperable with leach bearing plate vided with a central enlargement 15 having` spherical surfaces 16 on the opposite sides thereof.

The bracket B consists of two members 17-L17, each of which has a base flange 18 by which it is riveted or otherwise secured to the truck bolster, and an upstanding arm 19,'each arm being provided on its inner side with an enlargement or boss 20 having a concaved spherical surface 21 on its inner face, fitting and coperating with the cor'- responding spherical surface 16 on the enlargement 15. As clearly shown in Fig. 3, the thickness of the web 14 is'less than the distance between the edges 22-22 of the bosses 20, so that the roller C isnot only permitted a rotative movement about a horizontal axis, but can oscillate to accommodate itself to the varying angular relations of the body and truck bolster, the amount of oscillating movement of the roller being limited by the engagement of the web 14 with the circular edges 22, and if desired, the periphery of the roller` C may be so proportioned that the edges thereof as indicated at 23 will engage the inner surfaces 24. of the upstanding arms 17 to limit the oscillating movement of the roller.

From the preceding description it will be seen that the roller which I have provided is of relatively inexpensive construction and may be quickly applied to a bolster and when so applied, there is no danger of any of the parts becoming lost or displaced. Furthermore, all parts are or maybe in the form of castings to thereby minimize the cost of manufacture.

.I claim l. In a side Lbearing for railway cars, the combination with a cylindrical roller having a central web provided with a sphere-like enlargement, of means for rotatably and osing boss provided with a concave bearing with the inner edges of said bosses to limit surface on the inner face thereof, of a eylinthe oscillatable movement of said roller on dreal roller having a centrally disposed `said bracket.
